I noticed a while ago on the domain with lot’s of nice avatars.
It’s to easy to change a user avatar, without permission.
What high fidelity need is a dialog or something like that. And request if your avatar may be changed if a script want todo that. Then report the response back so the script can decide the next action. And only allow the change when you accepted.
It’s seems now way to easy to replce avatars.
Someday high fidelity is not controlled by cts. but by lot’s of foxes from @Menithal
